The lobby is a bit of a warren until you get used to it but I didn't find the pool too difficult to get to. Just a warning given I stayed the first day of Ramadan and there was a note saying they were moving the location of the reception desk for the duration of Ramadan (it hadn't moved yet as of when I checked out last week). Upgraded to a St. Regis Suite which was nice-ish but a bit dated. Service very good throughout, food quality also high.

Stayed at RC Doha for a few days previously and a bit of a toss-up as to which is the best hotel, both a strong contender for the best in Doha, I'd say (yet to try the new MO). St. Regis has a much nicer pool and public areas but the rooms are now dated. RC had good but not quite as perfect service and the pool in particular is less impressive (basically looks like what I always imagined a '5 star' hotel in Sharm El-Sheikh would be like), but the suites have been beautifully refurbished. St. Regis the marginally better location, but honestly both are pretty inconvenient for both downtown Doha and the airport.
